Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in the veterinary area - Test method and requirements (phase 2, step 1)
This document specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water or - in the case of ready-to-use products - with water. Products can only be tested at a concentration of 80 % or less, as some dilution is always produced by adding the test organisms and interfering substance.
The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used. This document applies to products that are used for equipment disinfection by immersion, surface disinfection by wiping, spraying, flooding or other means and teat disinfection in the veterinary area - e.g. in the breeding, husbandry, production, veterinary care facilities, transport and disposal of all animals except when in the food chain following death and entry into processing industry. This document also applies to products used for teat disinfection in these veterinary areas.
This method is not applicable to evaluate the activity of hand hygiene products. For these products reference is made to EN 14885, which specifies in detail the relationship of the various tests to one another and to "use recommendations".
NOTE This method corresponds to a phase 2 step 1 test.
Chemische Desinfektionsmittel und Antiseptika - Quantitativer Suspensionsversuch zur Bestimmung der bakteriziden Wirkung chemischer Desinfektionsmittel und Antiseptika für den Veterinärbereich - Prüfverfahren und Anforderungen (Phase 2, Stufe 1)
Dieses Dokument legt ein Prüfverfahren für und die Mindestanforderungen an die bakterizide Wirkung von chemischen Desinfektionsmitteln und antiseptischen Produkten fest, die bei Verdünnung in Wasser standardisierter Härte oder - im Falle gebrauchsfertiger Produkte - in Wasser als homogenes und physikalisch stabiles Präparat vorliegen. Die Produkte können nur bei einer Konzentration von höchstens 80 % geprüft werden, da durch die Zugabe der Prüforganismen und der Belastungssubstanz immer eine bestimmte Verdünnung auftritt.
Das beschriebene Verfahren soll der Bestimmung der Wirkung handelsüblicher Zubereitungen oder von Wirkstoffen unter den Bedingungen dienen, unter denen sie in der Praxis angewendet werden. Dieses Dokument gilt für Produkte, die für die Instrumentendesinfektion durch Eintauchen und bei der Oberflächendesinfektion durch Abwischen, Besprühen, Überfluten oder auf sonstige Weise sowie bei der Zitzendesinfektion im Veterinärbereich verwendet werden - z. B. bei der Aufzucht, Haltung, Produktion, in veterinärischen Pflegeeinrichtungen, beim Transport von Tieren sowie bei der Tierkörperbeseitigung aller Tiere mit Ausnahme der Tiere, die nach der Tötung direkt als Nahrungsmittel verwendet oder der weiterverarbeitenden Industrie zugeführt werden. Dieses Dokument gilt auch für Produkte, die bei der Zitzendesinfektion in diesen Veterinärbereichen verwendet werden.
Dieses Verfahren kann nicht angewendet werden, um die Wirkung von Produkten der Handhygiene zu überprüfen. Für diese Produkte wird auf EN 14885 verwiesen, die im Einzelnen den Zusammenhang zwischen den verschiedenen Prüfungen sowie zu den "Anwendungsempfehlungen" festlegt.
ANMERKUNG Dieses Verfahren entspricht einer Prüfung der Phase 2, Stufe 1.
Antiseptiques et désinfectants chimiques - Essai quantitatif de suspension pour l’évaluation de l’activité bactéricide des antiseptiques et des désinfectants chimiques utilisés dans le domaine vétérinaire - Méthode d’essai et exigences (phase 2, étape 1)
Le présent document spécifie une méthode d’essai et les exigences minimales relatives à l’activité bactéricide des produits antiseptiques et désinfectants chimiques qui forment une préparation homogène, physiquement stable, lorsqu’ils sont dilués dans de l’eau dure ou, dans le cas de produits prêts à l’emploi, dans l’eau. Les produits ne peuvent être soumis à l’essai qu’à la concentration de 80 % ou à des concentrations inférieures, car l’ajout des microorganismes d’essai et de la substance interférente s’accompagne forcément d’une dilution.
La méthode décrite vise à déterminer l’activité des formulations commerciales ou des substances actives dans les conditions d’utilisation. Le présent document s’applique aux produits utilisés dans la désinfection des équipements par immersion, la désinfection de surfaces par essuyage, pulvérisation, inondation ou d’autres moyens, la désinfection des trayons dans le domaine vétérinaire, par exemple dans la reproduction, l’élevage, la production, les services vétérinaires, le transport et l’abattage de tous les animaux, à l’exception de la chaîne alimentaire qui suit l’abattage et l’entrée dans l’industrie de transformation. Le présent document s’applique également aux produits utilisés dans la désinfection des trayons dans ces domaines vétérinaires.
Cette méthode ne s’applique pas à l’évaluation de l’activité des produits d’hygiène des mains. Pour ces produits, se référer à l’EN 14885, qui spécifie de façon détaillée les relations des différents essais entre eux et avec les « recommandations d’emploi ».
NOTE Cette méthode correspond à un essai de phase 2, étape 1.
Kemična razkužila in antiseptiki - Kvantitativni suspenzijski preskus za vrednotenje baktericidnega delovanja kemičnih razkužil in antiseptikov v veterini - Preskusna metoda in zahteve (faza 2, stopnja 1)
Ta evropski standard določa preskusno metodo in minimalne zahteve za baktericidno delovanje kemičnih razkužil in antiseptikov, ki tvorijo homogen, fizikalno stabilen pripravek, če so razredčeni s trdo vodo oziroma z vodo pri izdelkih, ki so pripravljeni za uporabo. Izdelke je mogoče preskušati samo pri 80-odstotni ali nižji koncentraciji, ker dodajanje preskusnih organizmov in moteče snovi vedno povzroči razredčenje.
Ta evropski standard se uporablja za izdelke v veterini, tj. pri vzreji, živinoreji, prevozu in odstranjevanju vseh živali, razen če so v prehrambeni verigi po smrti in so del predelovalne industrije.
Standard EN 14885 podrobno določa razmerje med različnimi preizkusi in priporočili za uporabo.
OPOMBA 1: Opisana metoda je namenjena določevanju dejavnosti komercialnih oblik ali aktivnih snovi pod pogoji, v katerih se uporabljajo.
OPOMBA 2: Ta metoda ustreza preskusu stopnje 1 faze 2.

Introduction
This document specifies a suspension test for establishing whether a chemical disinfectant or antiseptic
has a bactericidal activity in the fields described in the scope.
This laboratory test takes into account practical conditions of application of the product, including
contact time, temperature, test organisms and interfering substances, i.e. conditions which may influence
its action in practical situations.
The conditions are intended to cover general purposes and to allow reference between laboratories and
product types. Each utilization concentration of the chemical disinfectant or antiseptic found by this test
corresponds to defined experimental conditions. However, for some applications the recommendations
of use of a product may differ and therefore additional test conditions need to be used.
1 Scope
This document specifies a test method and the minimum requirements for bactericidal activity of
chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation
when diluted with hard water or - in the case of ready-to-use products - with water. Products can only be
tested at a concentration of 80 % or less, as some dilution is always produced by adding the test
organisms and interfering substance.
The method described is intended to determine the activity of commercial formulations or active
substances under the conditions in which they are used. This document applies to products that are used
for equipment disinfection by immersion, surface disinfection by wiping, spraying, flooding or other
means and teat disinfection in the veterinary area – e.g. in the breeding, husbandry, production,
veterinary care facilities, transport and disposal of all animals except when in the food chain following
death and entry into processing industry. This document also applies to products used for teat
disinfection in these veterinary areas.
This method is not applicable to evaluate the activity of hand hygiene products. For these products
reference is made to EN 14885, which specifies in detail the relationship of the various tests to one
another and to “use recommendations”.
NOTE This method corresponds to a phase 2 step 1 test.
